I actually have no hope of getting the Lightning card this way because a lot of people will realize it.
All you really need to do is get 3 buddies who doesn't care about Lightning to play 10 tournament matches and purposely lose the last 5 to you. Since their Elo are higher, you'll get a shit ton of points as I was getting 120+ from my friend that had won 1 game out of 1 game.
*EDITS*
To cheese it harder, the three people you get 5 free wins should get 10 free wins each to have even higher elo.
